Performance:
1. Temperature range -100°C~room temperature (temperature controllable)
2. Temperature control accuracy ±2°C
3. Temperature Uniformity ±3°C
4. Cooling rate 1~20°C/min, temperature controllable
Constructions:
1.Opening method of the box door: adopt horizontal upper opening cover, and use gas spring to assist opening
and closing the door.
2.Door seal: special low-temperature resistant sealing device to ensure that the door can be opened freely
under ultra-low temperature
3.Freezing medium: liquid nitrogen (user-provided, non-recyclable)
4.Exhaust system: when the pressure in the box is slightly positive, it will be automatically discharged
Controller:
The touch screen provides programmable control & makes the operation and input more convenient. It adopts
human-machine interface, programmed intelligent control, and has PID automatic adjustment function. It can set multi-stage cooling and heating programs. After all programs are completed, it will automatically alarm and power off.
The system also has its own process curve saving function, and the process curve can be downloaded via USB-disk.
Safety:
1. Electrical interlock.
2. With phase sequence protection function.
3. With over-temperature protection function.
4. With process curve setting function.
5. With timing function.
6. Equipped with equipment grounding protection function.
7. With safety pressure relief function.
8. Equipped with equipment caster movement and braking functions.
